The owner of the letter had left his family's information behind, but after so many years, his letter had been left in the cabin. It was only when the trial-takers arrived that it was fated to see the light of day again.
This was a warning letter to the adventurers from the outside world. These people who first entered the lost city and held on to their bottom line were eventually trapped in the cabin and died, unable to spread the key information about the lost city.
As long as this news did not spread to the outside world, the adventurers who went to the lost city would be endless, and eventually become the food supply and servants of the mother parasite.
